Question

这是jsp页面中一个调用get url的锚标记，从这个url我转发到post请求 CALL1 call1url在控制器中点击了一个get请求

@RequestMapping(value = "/call1url", method = RequestMethod.GET)
    public String make(HttpServletRequest request) {

        return "forward:/manctril";

    }

转发到控制器中的帖子请求

@RequestMapping(value = "/main", method = RequestMethod.POST)
        public String make2(HttpServletRequest request) {

            return "forward:/dash";

        }

尝试执行上述操作会返回类似于

的错误

There was an unexpected error (type=Method Not Allowed, status=405).
Request method 'GET' not supported

我的尝试是否可行，或者是否失败

我不认为可以使用redirect or forward从服务器进行GET到POST调用，您需要重新设计您的解决方案。您可以尝试使用以下方式实现它：

一个。你锚定Tag使用JS或AJAX对控制器进行POST调用，然后从一个POST到另一个POST可以完成，如下所示通过设置请求属性

request.setAttribute(View.RESPONSE_STATUS_ATTRIBUTE, HttpStatus.TEMPORARY_REDIRECT);

@RequestMapping(value = "/call1url", method = RequestMethod.POST)
    public String make(HttpServletRequest request) {

        request.setAttribute(View.RESPONSE_STATUS_ATTRIBUTE, HttpStatus.TEMPORARY_REDIRECT);
        return "forward:/main";

    }

    @RequestMapping(value = "/main", method = RequestMethod.POST)
    public String make2(HttpServletRequest request) {

        return "dash";

    }

湾您的锚点标记应该转到GET调用，该调用应该呈现一个jsp / html页面然后autosubmit jsp作为POST在页面/正文加载，如下所示，

<body onload="document.forms['redirectToURLForm'].submit()">

<form:form method="POST" id="redirectToURLForm"
        name="redirectToURLForm" action="main">
</form:form>

</body>

这将调用POST /main方法。

jattempting转发get请求到post请求返回不支持错误Spring
